通过对规范的特殊选择，具有一种夸克味的QCD 2 [SU（N）]被重铸为玻色形式。研究了弱（g m）和强（g m）耦合机制。前者被证明是SU（N）对称的约束相，其中束缚态具有弦状配置与字符串表示的电涡线，普通的介子和重子出现的电弦的纵向模式。强耦合机制描述了希格斯相位的剩余对称性[U（1）]N−1 <$SN，其中左因子和右因子分别是SU（N）的最大阿贝尔子群和N个夸克的置换群;粒子谱由SN多重态组成，[Uw（1）]N− 1电荷被捕获。
By means of a special choice of gauge QCD2[SU(N)] with one flavor of quarks is recast into the Bose form. Weak (g ⪡ m) and strong (g⪡m) coupling regimes are studied. The former is shown to be the SU(N)-symmetric confining phase in which bound states possess stringlike configurations with strings being represented by electric vortex lines; the ordinary mesons and baryons appear as longitudinal modes of electric strings. The strong coupling regime describes the Higgs phase with the residual symmetry [U(1)]N−1⊗ SNwhere the left and right factors are the maximal abelian subgroup of SU(N) and the permutation group of N quarks, respectively; the particle spectrum consists of SNmultiplets and the [Uw(1)]N−1charges are trapped.
